Persons of Interest: A Novel

by Peter Grainger

DC Smith has solved hundreds of crimes, but he’s never been accused of one ... until now.

In the peace and tranquility of the woods at Pinehills on a Saturday afternoon, a phone begins to ring. The phone belongs to DC Smith, and it isn’t unusual that the call is from Kings Lake Central police station; what is unusual is the fact that he seems to be the subject of an investigation rather than taking part in one. 

What's the link between a prisoner’s violent death in another county, the disappearance of two teenagers and the highest profile case in Kings Lake for many years? 

As Smith and his team begin to untangle the threads, one thing becomes clear—they are dealing with some of the most dangerous people that they have ever encountered.
